LAM P-COLLAR.

EZECIFICAIION forming part of Letters Patent No. 312,385, dated February 1'7, 1885.

Application tiled February 2.1, 188 1. (No model.) Patented in Germany January 8, 1884, No. 25,404.

To all whom it nuty cancer/t.-

Beit known that I, AUGUST RINOKLAKE, of

Brunswick, in the Empire of Germany, have invented a certain new and useful Improve ment in Apparatus for Preventing Sweating of Petroleum-Lamps, of which the following is a specification.

My invention relates to improvements in lamps, especially such as are used for hydrocarbon oils, in which the burner is screwed or secured within a socket or. collar upon the bowl or basin; and the object of my invention is to prevent the oil from oozing through the plaster or other material by which the metal collar or socketis generally fastened upon the glass bowl.

In the accompanying drawings, Figure 1 is a vertical section of a lamp embodying my improvement. Fig. 2 is a vertical section of a collaror socket to be mounted upon the neck of the glass bowl. Fig. 3 is the same metal collar seen from below; and Fig. 4 is a vertical section of a detail thereof, enlarged.

In carrying out my invention I arrange a hollow ring or collar. (1, upon the neck of the lamp reservoir. Said collar is screw-threaded upon its inner side to receive the burner. The upper part of the hollow ring or collar (1, I till with glue, gum, cork, or similar substance, I), which is impermeable by petroleum or oil. The lower part of the hollow ring a, or that part which surrounds the neck of the lamp reservoir upon its sides, I fill with plaster-0tparis or similar material, 0, in the usual or any other suitable manner. By this arrangement oil cannot ooze through the pores of the plaster.

In order to prevent any escape of petroleum along the shalt of the pinion or pinions by which the wick is raised or lowered, I have arranged a shell, d, soldered to the burnershell, and in the said shell (I, I have arranged an elastic packing, e, which is compressed by a screw fitting into the shell (I, and is thereby forced to bear against the pinion-shaft and against its seat within the shell, thus preventing any oil from coming forth from the wick along the pinion-shaft. The said packing 6 may conveniently consist of glue properly prepared for the purpose, of rubber, cork, or u similar matter, preferably resisting to petroleum.

\rVhat I claim as my invention, and desire to I secure by Letters Patent, is

1. In a lamp, the combination of a lampreservoir having a neck or rim and a hollow collar or ring adapted to fit about said neck, and containing near its upper portion packing impermeable to oil, said collar or ring being secured-to the neck or rim by plaster or similar substance, substantially as specified.

2. In a lamp, the combination of a lampreservoir having a neck or rim, the collar or ring (1, adapted to be secured about said neck or rim, the packing b, impermeable to oil, and the plaster c, substantially as specified.

The above speciti cation of my invention signed by me this 24th day of May, A. D1883.
